Honestly, I've only used it in my kamado. It does shut down well and re-use well. KBB does for me in the kettle too.
I'd start with your normal load, then see how much less you use on a cook.
I should add that, while that is my favorite lump, I do not use it often as it is also the most expensive. I use a Lazarri lump that is, at least near me, much cheaper.
